Wireless Chatting Using RF
In WIRELESS CHATTING USING RF project we are sending a message to the RF receiver through RF transmitter using SMS keypad. The use of SMS keypad is to create a message which is to be transmitted from the RF transmitter to the RF receiver. We are generating a message using SMS keypad which is to be send messages with the help of Microcontroller. As soon as the RF transmitter transmits messages they are displayed on LCD screen. A 433MHZ frequency carrier signal is generated by RF transmitter which is send using antenna. The message that was transmitted by the antenna at the transmitter side is received by the antenna at the receiver side, received message is taken by RF receiver which works on TLP434A transmitter at a frequency range of 433.92MHZ.The resulted message from the RF receiver is received by the microcontroller serially. The message is decoded and displayed on the LCD at the receiver side.
